The current application claims a priority to the U.S. Provisional Patent application Ser. No. 62/166,555 filed on May 26, 2015.

FIELD OF THE INVENTION

The present invention relates generally to electricity generation. More particularly, the present invention relates to conversion of a vehicle's wheel rotational energy into electrical energy.

BACKGROUND OF THE INVENTION

Semi-tractor trailers have refrigeration units that cool frozen containers at around 35 degrees Fahrenheit or below. Commonly, the refrigeration unit is powered by a diesel engine generator separate from the engine of the tractor unit. As such, these diesel engine generators could take up valuable space and require diesel in order to run. Also, diesel engine generators produce emissions in addition to the emissions already released by the engine of the tractor unit. There exist electrical systems that produce zero emissions and can take up less space than the diesel engine generators. In addition, there exists mounted alternators that can transfer rotational energy from a wheel into electrical energy. However, none of the prior art is specifically adapted to a semi-tractor trailer in order to constantly charge a Lithium battery that's charges a DC motor to power refrigeration units.

It is therefore an objective of the present invention to introduce a wheel powered alternator charging system for use on a semi-tractor trailer in order to power and charge a refrigeration unit. The disclosed invention will allow the constant charging of a Lithium battery that will power a DC motor in order to run the refrigeration unit. The alternator provides sufficient amps to constantly run the motor, and the excess amps will be used to charge the battery. The device can be mounted on the bottom of a semi-tractor trailer and can be attached to one set of the trailer wheels in order to harness the rotational motion energy from the wheel when the truck is being driven. The alternator charging system will be a universal unit with adaptable mounting capabilities. The device will function quietly in order to be used in quiet zones. Also, the device will be able to function in foul weather such as rain and snow. Alternative embodiments of the device can be adapted in order to charge batteries that power any electrical system on a semi-tractor trailer. Overall, the wheel powered alternator charging system promotes the charging of a battery that powers an electrical system for a refrigeration unit on a semi-tractor trailer.

The wheel powered alternator charging system can be adapted for use in different electrical systems (not specifically refrigeration units) and can be configured for mounting on different semi-tractor trailers on different sets of trailer wheels. The electrical system is quiet enough to be used in quiet zone areas and is durable in order to work well in any foul weather such as snow. Before explaining at least one embodiment of the present invention in detail, it is to be understood that the invention is not limited in its application to the details of the components and arrangements as described or illustrated. The invention is capable of other embodiments and of being utilized and carried out in various ways. It is also to be understood that the phrasing and terminology employed herein are for the purpose of description and should not be regarded as limiting. As such, the present invention is primarily used for the purpose of charging an electrical system by means of a system of pulleys, belts, and an alternator attached to one set of wheels of a semi-tractor trailer.

Referring to FIGS. 1-5, the preferred embodiment of the present invention generally comprises a support frame 1, a mounting bracket 2, an alternator 3, an input wheel 4, a pulley system of a first pulley assembly 5 and a second pulley assembly 6, a transfer shaft 7, at least one shaft support 8, and at least one bearing 9.

The support frame 1 is an arrangement of structural members that provides support and arrangement for the majority of the components of the present invention. The main support frame 1 is the component that houses the components and is attached to the underneath of a semi-tractor trailer or other vehicle. The material of the support frame 1 is not of specific importance to the present invention, so long as the support frame 1 is sufficiently strong enough to withstand the forces and stresses of supporting the rest of the components of the present invention and those encountered during operation. In one embodiment, the components of the main frame are welded together. However, in alternative embodiments, the components of the support frame 1 can be assembled or attached by different means such as nuts and bolts.

The alternator 3 may be any brand, model, type, shape, size, or configuration of alternator 3 or other device capable of generating electricity by converting rotational energy into electrical energy which possesses the characteristics, specifications or other traits sufficient to facilitate the spirit and purpose of the present invention. In one embodiment, the alternator 3 is a brushless 51 volt, 280 amp alternator 3. In other embodiments, other relevant and useful alternators may be utilized. The alternator 3 comprises an input shaft, to which an alternator wheel 31 is connected to be used with the pulley system. As the alternator wheel 31 turns, so does the input shaft, generating electricity. The alternator 3 is mounted to the support frame 1 through any useful means. In one embodiment, the alternator 3 is mounted to the support frame 1 by two alternator 3 stand mounts. In one embodiment, the alternator 3 stand mounts have a lower base portion and an upper circular portion, the upper circular portion encircling the alternator 3 to hold the alternator 3 in place. In one embodiment, the energy from the alternator 3 is used to charge a battery that powers a motor that runs a refrigeration unit.

The mounting bracket 2 enables the present invention to be mounted underneath a vehicle in order to connect the present invention to a wheel of the vehicle in order to capture the rotational energy of the vehicle's wheel to be converted into electrical energy utilizing the present invention. The mounting bracket 2 is connected to the support frame 1 opposite the pulley system. In various embodiments, the mounting bracket 2 may be connected to the support frame 1 in any useful location.

The input wheel 4 is a circular frame that is attached to the vehicle wheel to facilitate capture of the rotational energy of the vehicle wheel for transfer to the alternator wheel 31 through the pulley system. The pulley system functions to capture the rotational energy of a vehicle wheel to be transferred to the alternator 3. In various embodiments, the pulley system may comprise various pulley arrangements, but the pulley system comprises at least one pulley assembly. Various embodiments may utilize more than one pulley assembly, such as, but not limited to, two pulley assemblies, three pulley assemblies, or more than three pulley assemblies. More particularly, in one embodiment, the pulley system comprises a first pulley assembly 5 and a second pulley assembly 6.

The first pulley assembly 5 is rotationally engaged between the input wheel 4 and the transfer shaft 7, and the second pulley assembly 6 is rotationally engaged between the alternator wheel 31 and the transfer shaft 7 opposite the first pulley assembly 5 along the transfer shaft 7. Thus, the input wheel 4 is rotationally engaged with the alternator wheel 31 through the first pulley assembly 5, the transfer shaft 7, and the second pulley assembly 6.

Each of the at least one support shaft is connected to the support frame 1, and each of the at least one bearing 9 is connected within one of the at least one shaft support 8. The transfer shaft 7 is rotationally engaged within each of the at least one bearing 9, so that the transfer shaft 7 is supported on the support frame 1 by the at least one bearing 9 and the at least one shaft support 8. More particularly, the at least one shaft support 8 comprises a first shaft support 81 and a second shaft support 82, and the at least one bearing 9 comprises a first bearing 91 and a second bearing 92. The first bearing 91 is connected within the first shaft support 81, and the second bearing 92 is connected within the second shaft support 82. The first bearing 91 and the second bearing 92 internally receive the transfer shaft 7, supporting the transfer shaft 7 and reducing rotational friction of the transfer shaft 7.

Thus, the input wheel 4, being affixed to the vehicle wheel, is driven at the same angular speed as the vehicle wheel. As the input wheel 4 turns, the first pulley assembly 5 is driven, in turn rotating the transfer shaft 7, the second pulley, and finally the alternator wheel 31. A first axis of the input wheel 4, a second axis of the transfer shaft 7, and a third axis of the alternator wheel 31 are all oriented parallel to each other for efficient transfer of rotational energy from the input wheel 4 to the alternator wheel 31.

In one embodiment of the present invention, the support frame 1 comprises an upper portion 11, a lower portion 12, and a vertical portion 13. The upper portion 11 is perpendicularly connected to the vertical portion 13, and the lower portion 12 is perpendicularly connected to the vertical portion 13 opposite the upper portion 11 along the vertical portion 13, generally forming a right-angled zig-zag shape, with two opposing 90-degree alternate interior angles, and with the upper portion 11 being oriented parallel to the lower portion 12, vertically separated by the vertical portion 13. It is contemplated that the aforementioned geometrical relations are not necessarily required in all embodiments, however, and alternate configurations for the support frame 1 may be utilized as desired or required for a given application or situation. The alternator 3 is mounted to the upper portion 11. Each of the at least one shaft support 8 is perpendicularly connected to the lower portion 12. The mounting bracket 2 is connected to the vertical portion 13 opposite the lower portion 12, vertically between the upper portion 11 and the lower portion 12. Alternatively stated, the mounting bracket 2 is connected to the back side of the vertical portion 13, under the upper portion 11 of the support frame 1. In one embodiment, the support frame 1 further comprises a plurality of support gussets 14 that are connected between the upper portion 11, the vertical portion 13, and the lower portion 12 to provide structural integrity to the support frame 1.

More specifically in reference to the pulley system, in one embodiment, the first pulley assembly 5 comprises a first pulley belt 51 and a first pulley wheel 52, while the second pulley assembly 6 comprises a second pulley belt 61 and a second pulley wheel 62. The first pulley wheel 52 is concentrically connected to the transfer shaft 7, and the first pulley belt 51 is operatively connected between the input wheel 4 and the first pulley wheel 52. In one embodiment, the first pulley belt 51 is a v-belt, and the input wheel 4 and the first pulley wheel 52 comprise circumferential grooves into which the first pulley belt 51 is fitted, as is commonly known in pulley assemblies. It is contemplated, however, that the first pulley belt 51, the first pulley wheel 52, and the input wheel 4 may be configured for any type of pulley in alternate embodiments. Similarly, the second pulley wheel 62 is concentrically connected to the transfer shaft 7 opposite the first pulley wheel 52 along the transfer shaft 7, and the second pulley belt 61, being a v-belt, is operatively connected between the second pulley wheel 62 and the alternator wheel 31. The first pulley wheel 52 and the second pulley wheel 62 are positioned along the transfer shaft 7 at or near the respective extremities of the transfer shaft 7, with the first shaft support 81 and the second shaft support 82 being positioned along the transfer shaft 7 between the first pulley wheel 52 and the second pulley wheel 62.

The first pulley wheel 52 and the second pulley wheel 62 are rotationally fixed to the transfer shaft 7, so that the first pulley wheel 52, the second pulley wheel 62, and the transfer shaft 7 all rotate at the same angular rate. In one embodiment, the first pulley wheel 52 and the second pulley wheel 62 are rotationally fixed to the transfer shaft 7 through the use of radially off-center grooves and corresponding protrusions. Referring to FIG. 6, in one embodiment, the first pulley wheel 52 comprises a first groove 53, and the second pulley wheel 62 comprises a second groove 63, while the transfer shaft 7 comprises a first protrusion 71 and a second protrusion 72. The first protrusion 71 and the second protrusion 72 are laterally positioned on the transfer shaft 7 axially opposite each other along the transfer shaft 7. The first protrusion 71 and the second protrusion 72 are elongated strips of material traversing parallel to the axis of the transfer shaft. The first groove 53 axially and internally traverses through the first pulley wheel 52, and the second groove 63 axially and internally traverses through the second pulley wheel 62. The first protrusion 71 is positioned within the first groove 53 of the first pulley wheel 52, and the second protrusion 72 is positioned within the second groove 63 of the second pulley wheel 62, thus locking the first pulley wheel 52, the second pulley wheel 62, and the transfer shaft 7 into rotational alignment. The protrusions act as keys, and the grooves act as key holes, being locked together. In one embodiment, the aforementioned configuration is reversed, with the grooves traversing axially into the transfer shaft 7 at the outer surface of the transfer shaft 7, and the protrusions being correspondingly positioned internally to the apertures of the pulley wheels through which the transfer shaft 7 traverses.

The use of the pulley system allows a gear ratio to be designated from the input wheel 4 to the alternator wheel 31. In one embodiment, the diameter of the input wheel 4 has a 20 to 8 ratio to the diameter of the first pulley wheel 52, and the diameter of the second pulley wheel 62 has a 6 to 3 ratio to the diameter of the alternator wheel 31. Thus, the first pulley wheel 52 spins 20 times for each 8 rotations of the input wheel 4, and the alternator wheel 31 spins 6 times for each 3 rotations of the second pulley wheel 62, resulting in five rotations of the alternator wheel 31 for every one rotation of the input wheel 4.

The mounting bracket 2 allows the present invention to be connected to a vehicle frame.

The plurality of slots 220 traverses through the adjustment bracket 22, and are distributed across the adjustment bracket 22. In one embodiment, the plurality of slots 220 comprises four slots, which are arranged on the adjustment bracket 22 in a geometrically rectangular fashion. The adjustment bracket 22 is connected to the vertical portion 13 of the support frame 1 opposite the pulley system by a plurality of fasteners, such as, but not limited to bolts, each fastener traversing through one of the plurality of slots 220 into fastener receiving holes in the vertical portion 13 of the support frame 1. The slots are oriented parallel to the mounting hitch 21, and the horizontal alignment of the support frame 1 with the adjustment bracket 22 may be changed by changing the position of the bolts within the plurality of slots 220. FIG. 7 shows several views of a variation of the adjustment bracket shown in FIG. 5, which is a first embodiment of the adjustment bracket 22. FIG. 8 shows several views of a second embodiment of the adjustment bracket 22. The first embodiment of the adjustment bracket 22 shown in FIGS. 5 and 7 is designed to interface with a “spring style” vehicle frame or suspension.
